How do the ovulation tests work?

I am curious now. I see so many posts about ovulation tests... are they easy to get a hang of? Do you think it helps? Honestly, I see pictures with sooo many testing strips and its kinda overwelming, maybe bc I have no clue what it means. Did you get your BFP bc of the ovulation strips? I'm newish to ttc, I have learned alot over the past few months.. but you can never learn to much. I feel like I have a regular 27/28 DC, and I am pretty aware when I ovulate. Haven't been on BC for nearly 3 years, healthy 27 year old. I've wanted a baby and to be a mama since I was a little girl, so to finally have gotten married, and now ready for little ones I'm growing extremely impatient..
